Unveiling the Mystery of Gravity-Defying Hills

A YouTuber named Jim O'Shea recorded a video showcasing the anti-gravity effect at Magnetic Hill in Orrorroo, South Australia. However, the car isn't genuinely rolling uphill. Instead, an optical illusion caused by the lack of horizon reference points creates this mystifying effect. University researchers in Italy managed to recreate convincing anti-gravity slopes in a lab setting and discovered that "without a true horizon in sight," the human brain could be deceived by common landmarks such as trees and signs.
